rsh & perl -Directory creation not possible

[qazmlp]

I have a perl script which creates a directory in the local machine.
But, if I call this script from the remote machine using rsh, the
directory is not created. And there is no error message reported. Why
is that so ?

What is the remedy for this ?

Does the script make any assumptions about which dirctory it starts in?
Write debugging messages to /tmp

Does your script have something like?

mkdir '/path/to/dir' or die "Can not mkdir /path/to/dir $!\n";

If not, why not?

I have mkdir command in the script.
When the rsh was executed with 'mkdir' directly, it worked and the
directory was created. But, when the perl script(containing mkdir) was
executed, it did not work.

It is better to post the relevant chunks of code than merely to
describe them. In Perl, There Is More Than One Way To Do It, and there
may be a problem with the Way you have chosen.

You still haven't answered by previous question.

Post a relevant snippet of your code.

Here is an excerpt from the script:
$opath=$ProtName;
opendir(DIR,$opath) || system("mkdir $ProtName");
closedir (DIR);

I don't know whether it helps to find the cause of the problem.

Meanwhile, the problem was solved by selecting the option,
"execute all rsh commands as user: ", for rsh in remote machine.

Originally, I asked:


and you answered.

Yes, you have a mkdir, but you are forking out to do something that can be
done natively in Perl (as in my example) and you have no error checking.

Use the Perl mkdir with error checking, and then see what happens.

Not really. Perhaps you should replace the system("mkdir $ProtName")
with mkdir($ProtName) and then, if it fails, print out the reason that
it reports.
